Mason Hamrick is the latest installment of a historically successful pole vault program at Jefferson High. With Hamrick’s two state championships, including his most recent title this year, the Dragons have won 19 state titles in the pole vault dating back to 1964, making it one of the most successful events at a school with a multitude of track and field accomplishments over half a century. “We’re known for it, because most of the great pole vaulters that have come out of Georgia have gone through Jefferson,” Hamrick said.
